Attachment for heddle bars



LSQSQZS Feb. 21, 1933. 1, ANDREWS ATTACHMENT FOR HEDDLE BARS Filed Dec, l2, 1931 Patented Feb. 21, 1933 UNITED STATES ISAAC ANDREWS, OF SPARTANBURG, SOUTH CAROLINA yAfr'rnmanina'r ron HEDDLE Bans Application med December 12, k1931. seriai'nopesooa This invention relates to looms, and more particularly to the construction of the heddle bar, holding or securing device, forming a part thereof.

An important obj ect of the invention is the provision of a heddle bar securing device which will have a wide bar engaging surface, to the end that the connection between the securingdevice and heddle will be exceptionally strong and durable.

Another important obj ect of the invention is to provide a holder of a construction to permit the heddles to move thereover, without interference. n

A still further object of the invention is to provide a holder that may be readily and easily removed and replaced and one which will beY securely locked against accidental dis-4 placement.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made vwithin the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing: Figure 1 isa fragmental elevational view illustrating the upper rail of a heddle bar` securing device, constructed in accordance with the invention, one of the heddle bars having been removed.

Figure 2 is a vertical sectional view through the upper rail of the heddle frame, illustrating the securing device in elevation,

4d parts thereof being broken away.

Figure 3 is a sectional view taken on line 3-3 of Figure 1.

Referring to the drawing in detail, the reference character 5 designates the upper rail of a heddle frame, and while only the upper yrail of the frame is illustrated and described in the following speciication, it is to be understood that the securing device is to be employed in the lower rail of the heddle frame, with exactly the same relation to the lower heddle bar.

The support forming the subject matter of this invention, includes a bolt indicated by the reference character 6, which bolt is provided with a threaded portion 7 that extends through an opening formed in the rail 5.

Mounted on the threaded portion 7 of the bolt 6, is a winged nut, that rests on the upper edge of the rail, the winged nut being designed tomove'the bolt 6 through the rail 5, to adjust the heddle bar with which it has connection. Y

As clearly shown by the drawing, the bolt is provided with an enlarged portion 9 of rectangular formation, the front and rear edges of the enlarged portion being provided'with recesses to receive the metallic strips 10, that are formed with offset portions ll disposed intermediate the ends, the offset portions being fitted in the recesses. p

Portions of the walls of the recesses are punched inwardly and overlie the oset portions 11 of the metallic strips, 4as at 12, to secure the metallic strips in position against accidental displacement.

The heddle bars 13 that are secured to the rail 5, by means of the securing device are formed with elongated openings of lengths to receive the metallic strips l0 in such a way that a close fit between the heddle bars and metallic strips, will be insured at all times.

@wing to the construction of the metallic strips, the surfaces of the heddle barswill lie flush with the surfaces of the metallic strips 10 to the end that the heddles, which are supported on the heddle bars, and which are in dicated by the reference character 14,Smay slide over the heddle bars without interference on the part of the metallic strips.

Slidably mounted on the enlarged. portion of the bolt, is a disk indicated by the reference character 15, which disk is formed with fingers 16 that are slightly oifset, so that they will fit over the heddle bars at opposite sides of the enlarged portion 9, and secure the heddle bars against movement with respect to the bolt.

vA coiled spring indicated by the reference character 17 has one of its ends contactingv with the nut 18 that is positioned on the bolt.

7 to secure the bolt to the rail of the frame,

while the opposite end of the spring contacts with the disk 15, to force the disk and fingers 16, to their active or guarding positions. From the foregoin it will be seen that due 5 to the construction o the heddle bar securing or supporting device, the T-shaped construction of the securing device presents an exceptionally broad holding surface, thereby greatly strengthening the heddle frame wit the result that the heddle frame will withstand the severe strain directed thereto, and caused by the vibrations of the loom While in operation. 1

It is believed that in view of the foregoing detailed disclosure, a further detailed description as to the operation of the device is unnecessary.

Havin thus described the invention what is claime is:

1. In a heddle supporting frame, heddle bar supporting means, comprising a securing bolt extended through the frame, heddle bar securing members on the bolt and fitted in openin s formed in the heddle bars, and the sides othe heddle bar securing members being fiush with the sides of the heddle bars to permit the heddles to slide thereover.

2. In a heddle supporting frame, heddle bar supporting means comprising a bolt extended througl the frame, a T-shaped head on the bolt and o'set with respect to the bolt,

said T-shaped head being fitted in an elongated openmg ofthe heddle bar, and the side surfaces of the head being iush with the side surfaces of the heddle bar.

3. In a heddle supporting frame, a heddle bar suporting means comprising a bolt extended through the frame, elon ated members extending transversely of t e bolt and 49 fitted in elongated openings formed longitudinally of the heddle bars, and means overlfvin the elongated members and heddle bars or olding the elongated members in the elo ated openings.

4. In a heddle supporting frame, heddle bar supportin means comprising a bolt extended throug the frame, elongated members secured to the bolt, said elon ated members being fitted in elongate o enings formed in the heddle bars, and the si e faces of the'elongated members being Hush with the side faces of the heddle bars.

5. In a heddle supporting frame, a lieddle bar supporting means comprising a bolt extended through the frame, horizontally disposed members mounted on the bolt near one end thereof, heddle bars having elongated o nings to receive the horizontally disposes members, and a guard overl ing the orizontally disposed members and heddle bars for securing the heddle bars against displacement.

6. In a heddle supporting frame, heddle bar supportin means comprising a bolt ex- #5 tended throng the frame, elongated members extended transversely of the bolt, near one end' thereof and extended an appreciable distance beyond the sides of the bolt, heddle bars having elongated openings within which the elongated members fit to secure the heddle bars to the bolt, and means for holding the elongated members within the openin 7. In a heddlesupporting frame, hed le bar sup orting means comprising a bolt elongated) members arranged in paralle spaced relation withv each other .and secured to the bolt, said elongated members being fitted in elongated-openin of the heddle bar, said elongated members ein of thicknesses equal to the thicknesses of t e heddle bars, and yieldable means for locking the elo ted members-within the openings of the ed`- dle bars. Y

8; In a heddle supporting frame, a heddle bar supportin means comprising a bolt extended throug the frame, transversal disposed members secured to the bolt, sai heddle bars having elongated openings to Vreceive the transversely dis osed members, a guard slidable longitudina y of the bolt and movable to a position to overlie the heddle bars and transversely disposed members, and yieldable means for urging the guard to its active position.

9. In a heddle supportin frame, a heddle bar support comprlslng a ody portion secured to the frame, a connecting member on the body portion and fitted in an opening in the heddle bar, and means overlying the connecting member to guard a ainst accidental 190 displacement of the connecting bar and heddle bar.

v10. In a heddle supporting frame, ai heddle bar support comprising a body portion secured to the heddle frame, a connecting 106 member on the free end of the body ortion and fitted in an opening of the heddle bar, the outer surface of the connectin member being fiush with the outer surface o the heddle bar, andv means for holding the connectllo ing member in position.

In testimony that I claim the foregoing as my own, I have hereto aixed m si ature.'
